    To improve the stability margin of the power grid under unconventional conditions and enhance the fault emergency support capability of AC/DC grids, this paper investigates multi-resource and multiobjective collaboration damping control strategy method based on a multi-input multi-output (MIMO) system model by improving the existing robust damping control methods and considering the multiple control impacts. Based on the analysis of system oscillation characteristics, appropriate feedback signals and controller installation locations are selected based on the modal ratio index. Power control is performed using LCC-HVDC and energy storage systems. Finally, a coupled robust controller based on energy storage and DC transmission is studied according to the robust mechanism. Simulation results show that compared to other traditional damping controllers, the controller designed in this chapter is more suitable for system conditions with large perturbations and uncertainties.
